GRBModel.Set()
Set the value(s) of a parameter or attribute. Use this method for parameters, for scalar model attributes, or for arrays of constraint or variable attributes.
void | Set ( | GRB.DoubleParam | param, |
double | newvalue ) |
Set the value of a double-valued parameter.
The difference between setting a parameter on a model and setting it on an environment (i.e., through GRBEnv.Set) is that the former modifies the parameter for a single model, while the latter modifies the parameter for every model that is subsequently built using that environment (and leaves the parameter unchanged for models that were previously built using that environment).
Arguments:
param: The parameter being modified.
newvalue: The desired new value for the parameter.
void | Set ( | GRB.IntParam | param, |
int | newvalue ) |
Set the value of an int-valued parameter.
The difference between setting a parameter on a model and setting it on an environment (i.e., through GRBEnv.Set) is that the former modifies the parameter for a single model, while the latter modifies the parameter for every model that is subsequently built using that environment (and leaves the parameter unchanged for models that were previously built using that environment).
Arguments:
param: The parameter being modified.
newvalue: The desired new value for the parameter.
void | Set ( | GRB.StringParam | param, |
string | newvalue ) |
Set the value of a string-valued parameter.
The difference between setting a parameter on a model and setting it on an environment (i.e., through GRBEnv.Set) is that the former modifies the parameter for a single model, while the latter modifies the parameter for every model that is subsequently built using that environment (and leaves the parameter unchanged for models that were previously built using that environment).
